Description

The present invention relates to a window frame panel for use in buildings and a manufacturing method thereof.

Conventionally, a wall panel structure has been disclosed in which a lintel or window sill support is formed by cutting out the opposing surfaces of a vertical frame that is erected parallel to the upper and lower frames, and both ends of the lintel or window sill support are fixed to the lintel or window sill support to form an opening (see, for example, Patent Document 1).

Japanese Patent Application Publication No. 08-312026

However, the wall panel structure described in Patent Document 1 has the problem of poor airtightness because gaps are likely to occur between the lintel support or window sill support formed on the vertical frame and the fixed lintel or window sill support. In addition, gaps will occur if the opening formed by the vertical frame, lintel support, and window sill support is not finished with precision, so there is also the problem that skilled construction is required.

The present invention was made with an eye on these issues, and aims to provide a highly airtight and easy-to-install window frame panel and a manufacturing method thereof.

In order to achieve the above-mentioned object, the window-framed panel of the present invention is a window-framed panel that is attached to a frame by fitting the protrusion and the recessed portion around the periphery of the plate into a groove that is continuous in an annular shape inside the frame composed of vertical members and horizontal members, characterized in that it comprises a plate material having a concave-shaped flat surface with a rectangular cutout portion in the middle of one of the long sides of the rectangle and the rectangular cutout portion being smaller than the rectangle and having the intermediate portion as one side; an insulating board that is attached to one of the flat surfaces of the plate material with a protrusion that protrudes a predetermined length around the periphery of the plate material ; a window frame part that is rectangular in shape and has a groove that continues along the outer periphery of the plate material and into which the protrusion of the cutout portion is fitted; and a recessed portion that is fitted into the groove of the window frame part corresponding to the intermediate portion so as to protrude from the groove, the recessed portion being continuous with the protrusion of the one long side .

The window frame panel according to the present invention is attached to the frame by fitting the protruding parts and recessed parts around the periphery of the plate material into a continuous annular groove inside the frame, which is made up of vertical members such as columns and horizontal members such as beams and foundations. The protruding parts and recessed parts are fitted into the grooves, which improves airtightness. The window frame part has the protruding part of the cutout part fitted into the groove on the outer periphery, which improves airtightness. In addition, the window frame part is attached to the cutout part by fitting the protruding part of the cutout part into the groove on the outer periphery, so even if there is some dimensional error in the window frame part or the cutout part, this can be absorbed by the depth of the groove or the height of the protruding part, which makes construction easier. A sash window can be fixed inside the window frame part.

The method for manufacturing a panel with a window frame according to the present invention includes a panel attachment step of attaching an insulating board having a rectangular plane smaller than the plate material to one of the planes of the plate material with a rectangular plane, the insulating board being provided with a protrusion around the periphery of the plate material that protrudes a predetermined length from the insulating board, a notch step of cutting out rectangular shapes in the side intermediate portions of the plate material and the insulating board, respectively, by providing a window frame protrusion in the plate material that protrudes a predetermined length from the insulating board, and forming notches in the plate material and the insulating board, and a window frame attachment process for fitting the window frame portion into the cutout portion by fitting the window frame protrusion into the groove, and a fitting process for fitting a fitting portion into the groove of the window frame portion corresponding to the middle portion of the side so that the fitting portion protrudes from the groove , thereby connecting the protrusion and the fitting portion of the panel, the method being characterized by comprising : a window frame attachment process for fitting the window frame portion into the cutout portion by fitting the window frame protrusion into the groove, and a fitting process for fitting a fitting portion into the groove of the window frame portion corresponding to the middle portion of the side so that the protrusion and the fitting portion of the panel are continuous .

The manufacturing method of the window frame panel according to the present invention involves preparing an insulating panel in which an insulating board is attached to a board by a board attachment process, cutting out the middle part of the side of the insulating board and the board depending on the size and position of the window frame, and fitting the window frame into the cutout. The window frame can be easily attached by sliding it into the cutout.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in Figures 1 to 3, a window frame panel according to an embodiment of the present invention has a board material 10, a front reinforcing material 20, an insulating board 30, a frame material 40, a window frame portion 50, a support portion 60, and a rear reinforcing material 70.
The plate material 10 has a rectangular planar shape and has a concave shape with a rectangular cutout 11 at the middle of one of the long sides of the rectangular planar shape, the cutout 11 being smaller than the rectangle with one side at the middle part. The plate material 10 is made of plywood with aluminum film attached to both sides.

The front reinforcing member 20 is made of two rectangular pieces of material and is fixed to the plate material 10 along one of the longitudinal center lines of the plane of the plate material 10. The front reinforcing member 20 is fixed by providing protruding parts 12 that protrude a predetermined length from the upper end, lower end and cutout part 11 of the plate material 10. The protruding parts 12 may have packing attached thereto.
The heat insulating boards 30 are made of foamed resin and consist of three thick boards with rectangular flat surfaces. Each heat insulating board 30 is attached to one side of the flat surface of the board 10 in contact with the side of the front reinforcing material 20, and has a protruding portion 12 that protrudes a predetermined length around the periphery of the board 10. The protruding portion 12 of the cutout portion 11 constitutes a window frame protruding portion 12a. The heat insulating boards 30 have the same thickness as the front reinforcing material 20, and are continuous with the front reinforcing material 20 on the same plane.
The frame material 40 is fixed to the plate material 10 with protruding portions 12 protruding from the periphery, except for the notched portion 11, of the surface opposite the insulating plate 30. The frame material 40 increases the strength of the plate material 10, and the inside of the frame material 40 can be filled with insulating material such as glass wool.

As shown in Fig. 4, the window frame 50 is a rectangular frame made up of two horizontal members 51 and two vertical members 52, and has a continuous groove 53 at the center of the outer periphery. The horizontal members 51, 51 form a lintel and a window sill. The window frame 50 is fitted to the notch 11 by fitting the protruding portion 12 of the notch 11 into the groove 53. A packing material may be provided between the groove 53 and the protruding portion 12. The window frame 50 is continuous with the insulation board 30 and the front reinforcing material 20 on one side of the framed panel in the same plane.
The recessed part 60 is made of a long and narrow plate material 10 and is fitted into a groove 53 corresponding to the middle part of the window frame part 50 so as to protrude from the groove 53. The recessed part 60 protrudes from the groove 53 at the same height as the protruding part 12 of the plate material 10, and both ends are continuous with the protruding part 12.
The rear reinforcement material 70 has a vertical member 71 and multiple horizontal members 72 , and is fixed between the inner surface of the frame material 40 and the outer peripheral edge of the window frame portion 50 .
The components may be fixed using screws, adhesive or pressure sensitive adhesive.

The window frame panel is manufactured by the following process.
A front reinforcing member 20 is fixed to one side of the flat surface of the plate material 10, and an insulating plate 30 is attached to the flat surface of the plate material 10 in contact with the side of the front reinforcing member 20 (plate material attaching step). At this time, a protruding portion 12 that protrudes a predetermined length from the periphery of the insulating plate 30 is provided on the plate material 10. An insulating panel is manufactured by the plate material attaching step. The plate material 10 and the insulating plate 30 of the insulating panel are each cut out in a rectangular shape at the middle portions of the sides, to form a notch portion 11 in the plate material 10 and the insulating plate 30 (notch forming step). At this time, a window frame protruding portion 12a that protrudes a predetermined length from the insulating plate 30 is formed around the notch portion 11 of the plate material 10.

Next, as shown in FIG. 5, the window frame portion 50 is fitted into the cutout portion 11 (window frame mounting process). At this time, the window frame portion 50 is slid onto the window frame protrusion 12a to fit the window frame protrusion 12a into the groove 53 of the window frame portion 50. A packing material may be provided between the groove 53 and the window frame protrusion 12a. Next, the protruding portion 60 is fitted into the groove 53 of the window frame portion 50 corresponding to the middle portion of the plate material 10 so as to protrude from the groove 53 (protruding process). The frame material 40 is attached to the periphery of the surface of the plate material 10 opposite the insulation board 30 by protruding the protrusion 12 (frame mounting process). The back side reinforcement material 70 is bridged and fixed between the inner peripheral surface of the frame material 40 and the outer peripheral edge of the window frame portion 50 (reinforcement process). In this way, a panel with a window frame can be manufactured.

Next, the operation will be described.
The window frame panel is attached to the frame by fitting the protrusions 12 and the supporting parts 60 around the plate material 10 into the grooves that are continuous in an annular shape inside the frame, which is composed of vertical members 1 such as columns and horizontal members 2 such as beams and foundations. A packing material may be provided between the groove 53 and the protrusions 12. Since the protrusions 12 and the supporting parts 60 are fitted into the grooves, airtightness can be improved. The window frame part 50 has the protrusions 12 of the cutout part 11 fitted into the grooves 53 on the outer periphery, so that the airtightness is improved. In addition, the window frame part 50 is attached to the cutout part 11 by fitting the window frame protrusions 12a of the cutout part 11 into the grooves 53 on the outer periphery, so that even if there is some dimensional error in the window frame part 50 or the cutout part 11, it can be absorbed by the depth of the groove 53 or the height of the protrusions 12, making construction easier. A sash window can be fixed inside the window frame part 50.

In the manufacturing method for a panel with a window frame, an insulating panel is prepared by attaching an insulating plate 30 to a plate material 10 in a plate material attachment process, and then the insulating plate 30 and the middle part of the side of the plate material 10 are cut out according to the size and position of the window frame portion 50, and the window frame portion 50 is fitted into the cutout portion 11 for installation. The window frame portion 50 can be easily attached by sliding it into the cutout portion 11. This makes it easy to manufacture a panel with a window frame.

Generally, installing and constructing windows requires a lot of labor and time, which has a significant impact on the quality of the house. Windows, in particular, are an important construction point in ensuring airtightness in highly insulated and airtight houses. Panels with window frames make it easy to install and construct windows, and can significantly shorten the construction period. Furthermore, panels with window frames allow high-quality construction even by unskilled craftsmen, and can reliably maintain airtightness even in highly insulated and airtight houses. The size of the window can be freely set by changing the size of the window frame portion 50 within the range of the width and height of the panel with window frames.
